I bought a ton of stuff at auction, but at the end of each auction, the auctioneer sends me a strongly-worded message indicating that my new possessions must be removed from their premises immediately or I will be charged by the day.
Their premises are on the other side of the country, so I have to contract with a shipping provider. This I do (thank you ParcelForce), and the package is picked up and brought to me.
The logistics are intimidating from a distance, but actually this turns out to be one of the less problematic parts of this entire process.
